Hi,
I don't play piano so this question might be really dumb.
This afternoon we received our Kawai K25 piano. I notice something that I didn't notice at the store: when the sustain pedal is depressed, and you hit a higher note, you hear a buzzing that reverbs as long as the pedal is pressed. The middle notes are not as obvious, and the lower notes are not perceptible, but I suspect it's there also. If I hit a note, *then* press on the sustain pedal, I don't hear the buzz.
My analysis says this buzz cannot be avoided since all the dampers are lifted when the sustain pedal is depressed. When you hit a note, all other strings will vibrate somewhat, and that might be where the buzz is from.
Am I right? Or is the instrument insufficiently damped to isolate strings for different notes to avoid such resonance?
Since I don't play the piano, I can't tell if one should ever depress the sustain pedal first before hitting a note or not.
Thanks and best regards,
Teng-Kiat
